Firefox and Flash Player Upgrade Issue

Gonna keep this short and sweet cos its covered elsewhere but was a pain for me so gonna blog it!

Task: Upgrade Flash Player from 9,0,45 to 9,0,47 in FireFox

Problem: When it comes to running a project from Flex Builder 2 an error message pops up stating:

*C:\Program Files\Mozilla Firefox\plugins\NPSWF32.dll

Flex Builder cannot locate the required version of the Flash Player. You may need to install Flash Player 9.0 or reinstall Flex Builder. Do you want to try to run your application with the current version?*

Solution: On installation of the Flash Player the NPSWF32.dll file is copied to C:\WINDOWS\system32\Macromed\Flash. Copy NPSWF32.dll to C:\Program Files\Mozilla Firefox\plugins\
